5411-52-9 Usage
General Description
1,2,3-triiodo-4-methyl-5-nitrobenzene is a chemical compound with the molecular formula C7H4I3NO2. It is a yellow crystalline solid that is used in organic synthesis and as a precursor to other organic compounds. The presence of three iodine atoms and a nitro group make it a highly reactive compound and it can be used in various chemical reactions, such as Suzuki coupling and palladium-catalyzed cyanation. It is also used as a raw material in the production of dyes and pigments. However, it should be handled with care as it is toxic and can be harmful if ingested, inhaled, or comes into contact with the skin.
Check Digit Verification of cas no
The CAS Registry Mumber 5411-52-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,1 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 5411-52:
(6*5)+(5*4)+(4*1)+(3*1)+(2*5)+(1*2)=69
69 % 10 = 9
So 5411-52-9 is a valid CAS Registry Number.

Iodination of nitroarenes by a superactive reagent based on iodine chloride
Chaikovskii, V. K.,Kharlova, T. S.,Filimonov, V. D.
, p. 1291 - 1294 (2007/10/03)
Iodine chloride reacts with Ag2SO4 in H2SO4 to give a new superelectrophilic reagent capable of iodinating nitrobenzene, halogenated nitrobenzenes, nitrotoluenes, and aromatic compounds with two nitro groups in the ring. Mononitroarenes are easily iodinated at 0-20 deg C, while dinitroarenes require heating to 100-170 deg C.
